Dear Consumer:

Thank your for contacting the Center for Auto Safety (CAS) about problems
with your General Motors “C” car (Buick Electra, Buick Park Avenue/Park
Avenue Ultra, Oldsmobile 98). After 1990, the Electra was dropped and
the Park Avenue, Park Avenue Ultra and 98 were completely redesigned for
1991. After 1996, GM dropped the Olds 98 leaving the Park Avenue the last
of a dying breed.

Although redesigned, the platform still is prone to problems such as
paint peel, seat belts, braking and steering loss. Nearly
all 1987-94 C-cars have door mounted automatic front door mounted
seat belts
. When left connected, as they should be, they make
entry and exit awkward, especially for older and handicapped people. Even
worse, the belts can’t keep occupants inside the car if a door opens in
a crash. In 1990, The National Highway Traffic Safety Administration (NHTSA)
refused CAS’ request to investigate this belt problem.

Peeling paint (1985-93) has been a costly problem to
take care of. In 1993 at CAS’ request, GM agreed to pay for complete repainting
for paint peel or delamination through six years and unlimited mileage.
In March 1995, GM secretly cut the policy to five years, but if pushed,
they will honor the six year policy.

Power steering loss when cold has long been a problem
in C-cars. In May 1989, GM issued a secret warranty that covered repairs
for the defect on 1985-88 C-cars for up to 5 years/50,000 miles, but failed
to notify most owners. Only customers who complained loudly enough were

The heating/air conditioning system in the Park Avenue
and Olds 98 after the 1991 model redesign can only be called torturous
with GM issuing service bulletin after service bulletin on problems ranging
from too much heat to not enough defrosting to whistles and thumps.

You’ll find information on these and other C-car defects below and what
you can do
about them plus a complaint
. Your information will help us build a strong case against GM
as we fight for action on these defects.

We need you to support the Center for Auto Safety in our fight for consumer
rights and against poorly designed and unsafe cars. Your contribution
is tax-deductible which
entitles you to our quarterly newsletter, Lemon Times. Please submit
the membership form along with your contribution
and complaint. If you contribute $35 or more, we will send you the current edition of The Ultimate Car Book, by Jack Gillis.
